Turns his young girlfriend into a submissive and buggers her on her birthday

His young girlfriend has been asking him for a while to prepare something special for her next birthday. And he has thought of something different, so he has told her that for one night she has to be a submissive who refuses nothing. He gags her so she can’t scream, gropes her in different ways and then he does something they haven’t done yet and he’s really looking forward to it: he penetrates her ass. The little slut knows she can’t complain and just screams with pain and pleasure as she feels her asshole being torn up for the first time.
